were taken out of service in the late 1950s. About 1970, the trains were almost sold to the Disney Company for $500 each, when Mabel Wilcox matched the price and kept the locomotives in Kauai. When Mabel Wilcox turned the Plantation she had inherited into the Grove Farm Museum in the 1970s, the four gauge locomotives were given to the museum. When she died in 1978, her estate included an endowment for the operations of the Museum, including the locomotives. They are currently listed in the National Register of Historic Places as Grove Farm Company Locomotives. The collection includes four locomotives, all of which saw extensive service on Kauai. Paulo Pride of place in the Grove Farm Museum locomotive collection is one of the earliest steam locomotives in Kauai, an 1887 Hohenzollern steam engine built in Düsseldorf, Germany for the Koloa Plantation for $4,000, which arrived in 1888. This engine is also notable because it is today the oldest steam locomotive in the state of Hawaii currently being run on rails; it pre-dates all steam locomotives in the State, in any condition, except for two: one is a gauge Baldwin Locomotive from 1883 that is said to be buried in a sand dune in Puunene, on the island of Maui; the other is the Claus Spreckels, dating from 1882, originally a coal-fired engine later converted to oil, which is in storage in Maui in operational condition. At one time, it was thought the first locomotive on Kauai was this 1887 engine. It is a wood-fired side-tank locomotive weighing some 10 tons and has a gauge. This engine is named Paulo, a tribute to Paul Isenberg, a wealthy sugar planter in the 1880s. Paul Isenberg spent many years in Kauai, arriving in 1858 and by 1862, at age 25, was manager of the Lihue Plantation, the second oldest plantation after Koloa. He greatly expanded the plantation and also was a partner in the Koloa sugar mill and the Kekaha sugar mill. He returned to his native Germany in 1878, leaving his brother Carl to assume his responsibilities at Lihue Plantation. Paul remained active in the business, however, and arranged for the immigration of 124 people from Germany to Kauai. The Paulo engine was shipped from Germany in 1887 to Koloa Plantation. Carl Isenberg started the Lihue Plantation Railway in 1891. The Paulo engine remained in active service hauling cane until 1920,
